Seaport Calibre Materials Acquisition Corp. (SCMAU) operates as a blank check company whose principal activity involves effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar initial business combination with one or more businesses, with a primary focus on opportunities in the steel, metals, and metals processing sector; it offers no other products or services beyond its special purpose acquisition company structure. The company, founded in 2019 and headquartered at 360 Madison Avenue, 20th Floor, New York, NY, targeted global operations without specified subsidiaries or parent relationships. In a major development, Seaport Calibre Materials redeemed its public shares and liquidated on February 1, 2023, after failing to complete an initial business combination within the required timeframe under its amended charter, following an unsuccessful stockholder vote on a proposed extension from February 1 to August 1, 2023; its units trade on Nasdaq post-liquidation with no active operations or new strategic initiatives reported.
